Title
Quantum Information
Abstract
Quantum information theory is a relatively young branch of theoretical physics. It analyzes the new possibilities which quantum systems, by the very structure of quantum mechanics, have to offer over classical ones regarding the transmission and processing of information. This talk attempts to give a concise view of the crucial differences between the quantum and the classical notions of information and correlation (entanglement). We will then look at some of the new possibilities provided by quantum systems in cryptography and computing, and sketch some of the emerging links between quantum computational complexity classes and statistical mechanics.
